Biology Anatomy

Question 1

Arteries

Answer 1

The arteries carry blood away from the heart
Usually 02 rich
It is a connective tissue and muscle
Walls are elastic and thick. They expand and contract

Question 2

Capillaries

Answer 2

Capillaries are a type of blood vessel
The capillaries carry blood from the arterioles to venules
Capillaries are the smallest blood vessels for gas exchange
Capillaries form a fine network through cells (capillary bed)

Question 3

Pharynx

Answer 3

The Pharynx is the passageway that connects the mouth and nasal cavity to the larynx and esophagus.

Question 4

Epiglottis

Answer 4

The epiglottis closes airway

Question 5

Trachea

Answer 5

The trachea is the tube that carries air from the nasal passages to the bronchi and then to the lungs (also known as a windpipe)

Question 6

Asthma

Answer 6

Asthma is a disease that affects your lungs. It narrows the airways by causing an allergy-induced spasms of surrounding muscles or by clogging the airways with mucus. Asthma causes wheezing, breathlessness, chest tightness and coughing at day or night.

Question 7

Microvilli

Answer 7

Microvilli are microscopic,finger-like projections found on the surface of certain cells. Their main function is to increase the surface area of the cell membrane which enhances the cells ability to absorb nutrients, ions and other substances from the surrounding environment.

Question 8

Tissues

Answer 8

Tissues are groups of specialized cells that work together to perform a specific function. They are the building blocks of organs and organ systems in living organisms.

Question 9

Organs

Answer 9

Organs are structures made of different types of tissues that perform a specific function within the body.

Question 10

Enzymes

Answer 10

Enzymes are biological molecules (proteins) that act as catalysts in biochemical reactions. Enzymes are involved in a wide range of biological processes including digestion, metabolism etc.

Question 11

Amylase

Answer 11

Amylase are a type of enzyme produced by the salivary glands in the mouth and the pancreas. Amylase breaks down complex carbohydrates into smaller molecules.

Question 12

Pancreas

Answer 12

The pancreas produces digestive enzymes that help break down food and releases hormones, such as insulin, which controls blood sugar.

Question 13

S.A Node

Answer 13

sets the rate and timing at which cardiac muscle cells contract

Question 14

Gas Exchange

Answer 14

Gas exchange is the transfer of oxygen into the blood, and carbon dioxide out of the blood. (This is the main function of the lungs).

Question 15

Exhaling and Inhaling

Answer 15

: Exhaling and inhaling are the processes involved in breathing which is the movement of air in and out of the lungs. Exhaling is the process of expelling air from the lungs. Inhaling is the process of taking air into the lungs.

Question 16

Red Blood Cells

Answer 16

Most abundant cells in blood. Their primary function is to transport oxygen from the lungs to body tissues and carry carbon dioxide back to the lungs for elimination.

Question 17

White Blood Cells

Answer 17

White blood cells play a vital role in defending the body against infection and foreign substances. They help to identify and destroy pathogens, produce antibodies, and regulate immune responses.

Question 18

Platelets

Answer 18

Platelets are cell fragments involved in blood clotting (hemostasis). When a blood vessel is damaged, platelets form a clot to prevent excessive bleeding.

Question 19

Plasma

Answer 19

Plasma transports nutrients, hormones and waste products throughout the body.

Question 20

Pulmonary Circuit

Answer 20

Carries blood between the heart and the lungs for oxygenation

Question 21

Systemic Circuit

Answer 21

Distributes oxygenated blood to the body’s tissues and returns deoxygenated blood back to the heart

Question 22

Valves

Answer 22

Valves help regulate and control the flow of blood. The main function of valves is to prevent the backward flow or reflux of blood.

Question 23

Peristalsis

Answer 23

Peristalsis are wavelike muscular contractions in the esophagus that pushes content forward.

Question 24

Vitamins and Minerals

Answer 24

Vitamins and minerals are essential nutrients required by the body in small amounts to support various physiological functions, growth, and overall health

Question 25

Macromolecules

Answer 25

Macromolecules are a very large molecule made up of smaller molecules that are linked together.

Question 26

Mechanical Digestion

Answer 26

Mechanical digestion is the physical breakdown of large pieces of food into smaller pieces via contractions, churning and mouth/beaks.

Question 27

Chemical Digestion

Answer 27

Chemical Digestion is the chemical breakdown of nutrient molecules into smaller molecules from enzymes.

Question 28

Liver

Answer 28

The liver performs important functions in the body, such as metabolism, detoxification, and the storage of nutrients.

Question 29

Diffusion Gradient

Answer 29

: Diffusion gradient is a dissolved substance that moves from a region of high concentration to low concentration
