A)The dermis
B)The epidermis
C)The integument
D)The epithelial tissue

Accepted Answer

Blood vessels, nerves, sweat and oil glands, and hair roots are found within the dermis layer of the skin, which is located beneath the epidermis.

Question 2

A)Organ systems
B)Organs
C)Mitosis
D)Chromosomes

Accepted Answer

Organs are formed by groups of tissues that work together to perform a specific function. For example, the heart is an organ composed of muscle tissue, connective tissue, and nervous tissue, all working together to pump blood throughout the body.

Question 3

Swallowing, coughing, and vomiting are controlled by which part of the brain?
A)Midbrain
B)Pons
C)Medulla
D)Cerebral cortex

Accepted Answer

The medulla is the part of the brainstem that is responsible for regulating vital functions such as breathing, heart rate, and blood pressure. It also controls reflexes such as swallowing, coughing, and vomiting.

Question 4

Which of the following is the working phase of the heart?
A)Pulse
B)Heart rate
C)Systole
D)Diastole

Accepted Answer

Systole is the phase of the heartbeat when the heart muscle contracts and pumps blood out of the chambers into the arteries. This is the working phase of the heart where blood is being actively circulated throughout the body. The other options, pulse and heart rate, are measurements of the heart's activity rather than specific phases, while diastole is the phase when the heart is relaxed and filling with blood.

Question 5

Which of the following is the largest systemic artery in the body?
A)The aorta
B)The carotid artery
C)The radial artery
D)The brachial artery

Accepted Answer

The aorta is the largest systemic artery in the body, originating from the left ventricle of the heart and extending down to the abdomen where it divides into two smaller arteries. The carotid artery supplies blood to the head and neck, while the radial and brachial arteries are smaller arteries located in the arm.

Question 6

What is the outer layer of the skin called?
A)The dermis
B)The epidermis
C)The epithelial tissue
D)The cytoplasm

Accepted Answer

The outer layer of the skin is called the epidermis. The dermis is the layer beneath the epidermis, while epithelial tissue is a type of tissue that can be found in various parts of the body, including the skin. Cytoplasm refers to the fluid substance that fills a cell, and is not a part of the skin.

Question 7

How many chromosomes are in each cell?
A)15
B)23
C)46
D)92

Accepted Answer

Most human cells contain 46 chromosomes (23 pairs) - 23 from the mother and 23 from the father.

Question 8

Which system is stimulated when a person is excited, exercising, or scared?
A)The central nervous system
B)The autonomic nervous system
C)The sympathetic nervous system
D)The parasympathetic nervous system

Accepted Answer

The sympathetic nervous system is responsible for the fight or flight response, which is activated during times of excitement, exercise, or fear. This system increases heart rate, dilates pupils, and inhibits digestion to prepare the body for action.

Question 9

Which part of the eye contains nerve fibres for vision?
A)Sclera
B)Cornea
C)Iris
D)Retina

Accepted Answer

The retina is the part of the eye that contains nerve fibers for vision. It is located on the inner surface of the back of the eye and is composed of layers of specialized cells that process visual information and send signals to the brain via the optic nerve.

Question 10

Mr.Yang has had a stroke.Prior to the stroke, he did crossword puzzles at a high level.He is finding it very hard to do them now, and he can't remember the words like he used to.What part of the brain would most likely be affected?
A)Cerebrum
B)Cerebellum
C)Midbrain
D)Brainstem

Accepted Answer

The cerebrum is responsible for higher brain functions such as language, memory, and problem-solving. Crossword puzzles require a high level of language and problem-solving skills, so damage to the cerebrum could cause difficulty in these areas.

Question 11

What is the basic unit of body structure called?
A)Cell
B)Nucleus
C)Organ
D)Organ systems

Accepted Answer

The basic unit of body structure is called a cell. Cells are the smallest units of life and are responsible for carrying out all the functions necessary to keep an organism alive.

Question 12

Where are blood cells formed?
A)Cartilage
B)Tendons
C)Bone marrow
D)Periosteum

Accepted Answer

Blood cells are formed in the bone marrow, which is the spongy tissue found in the center of bones. Other choices, such as tendons and periosteum, are not involved in blood cell formation. Cartilage does not have blood vessels or cells, and does not play a role in blood cell formation either.

Question 13

Which part of the cell directs the cell's activities?
A)The cell membrane
B)The cytoplasm
C)Organelles
D)The nucleus

Accepted Answer

The nucleus is the part of the cell that contains the cell's genetic material in the form of DNA. It directs the cell's activities by controlling the expression of genes through the production of RNA and proteins.

Question 14

Which one of these statements about the musculo-skeletal system is true?
A)It includes two different types of bone tissue.
B)It prevents free movement of the body.
C)It protects the body.
D)It helps regulate body temperature.

Accepted Answer

The musculo-skeletal system, which includes bones, muscles, tendons, and ligaments, functions to protect the body. The bones provide a rigid framework that protects internal organs, while muscles, tendons, and ligaments help stabilize and protect joints. None of the other statements are true.

Question 15

What is the waxy substance secreted by glands in the ear called?
A)Cerumen
B)Malleus
C)Incus
D)Cochlea

Accepted Answer

The waxy substance secreted by glands in the ear is called cerumen. Malleus, incus, and cochlea are all structures within the ear but do not refer to the waxy substance.

Question 16

Which structure carries messages to the brain?
A)The auditory nerve
B)The semicircular canals
C)The cochlea
D)The Eustachian tube

Accepted Answer

The auditory nerve carries sound information from the cochlea in the ear to the brain for processing. The semicircular canals are responsible for detecting changes in head position and movement, the cochlea is responsible for detecting sound, and the Eustachian tube helps regulate air pressure in the middle ear.

Question 17

Inherited traits are controlled by which of the following?
A)Organelles
B)Chromosomes
C)Genes
D)Sex cells

Accepted Answer

Inherited traits are controlled by genes, which are segments of DNA located on chromosomes. Organelles and sex cells play a role in cellular function and reproduction, respectively, but are not directly responsible for inherited traits.

Question 18

Which of the following are voluntary muscles?
A)Arm and leg muscles
B)Stomach muscles
C)Heart muscles
D)Intestinal muscles

Accepted Answer

Arm and leg muscles are voluntary muscles because we have conscious control over their movement. Stomach and intestinal muscles are involuntary muscles that work automatically without conscious control. Heart muscles are involuntary muscles, but they work autonomously and are controlled by their own specialized system, not by conscious control.

Question 19

Which of the following is the muscular part of the heart?
A)The pericardium
B)The myocardium
C)The endocardium
D)The ventricles

Accepted Answer

The myocardium is the muscular part of the heart, responsible for contracting and pumping blood through the various chambers and valves. The pericardium is the protective sac that surrounds the heart, while the endocardium is the inner lining of the heart's chambers. The ventricles are the two lower chambers of the heart, but they are not exclusively muscular.

Question 20

Which substance gives red blood cells their colour?
A)Oxygen
B)Carbon dioxide
C)Hemoglobin
D)Plasma

Accepted Answer

Hemoglobin is a protein found in red blood cells that contains iron, which binds with oxygen to transport it throughout the body. Hemoglobin also gives red blood cells their characteristic red color.
