Answer 3

Release hormones into the bloodstream

Question 4

Answer 4

This is small part of your brain that constantly monitors a number of the body parameters
Eg. Temperature, heart rate and blood pressure

Question 5

Pituitary gland

Answer 5

This is often called the mater gland because it releases hormones that stimulate other glands in the body- adrenal, thyroid, ovaries and testes

Question 6

Two parts of the pituitary gland

Answer 6

The anterior- front
Posterior - back

Question 7

The anterior gland produces hormones such as

Answer 7

Adrenocortropic hormone
Thyroid stimulating hormone
FSH
LH
prolactin

Question 8

FSH

Answer 8

Stimulates the growth of ovaries

Question 9

Anti diuretic gland

Answer 9

This directly acts on kidneys and blood vessels, controlling the amount of water content in blood

Question 10

Pancreas

Answer 10

This organ regulates the amount of glucose

Question 11

How does the pancreas regulate glucose

Answer 11

Produces hormones called insulin and glucagon

Question 12

Insulin

Answer 12

Allows glucose to be absorbed earthier by cells in the body or to be converted by glycogen and stored in the liver

Question 13

Glucagon

Answer 13

Causes the glycogen in the liver to be realeased into the blood

Question 14

Adrenal glands

Answer 14

produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions.

Question 15

Adrenaline

Answer 15

The hormone acts on most tissues in the body and is responsible for “fight or flight” response to a stressful suition situation

Question 16

There are two parts of the adrenal gland

Answer 16

Cortex - outer
Medulla- inner

Question 17

The medulla produces

Answer 17

Adrenaline

Question 18

The cortex produces

Answer 18

Cortisol
Aldosterone

Question 19

Cortisol

Answer 19

The so called hormone that gives the body a boost of energy in times of stress by controlling the way in which the body processes nutrients

Question 20

Aldosterone

Answer 20

This hormone instructs the kidney to remove or release certain salts from the blood. Regulates salts in the bloodstream

Question 21

Thyroid glands

Answer 21

The thyroid glands are responsible for metabolism

Question 22

Metabolism

Answer 22

How quickly chemical processes take place in the body which in turn determines how quickly boldly functions such as digestion take place.

Question 23

Two thyroid gland secretes two hormones

Answer 23

T3 and t4
Which cause the body cells to work faster

Question 24

The thyroid also produces another hormone

Answer 24

Calcitonin which acts in opposition to the para thyroid gland

Question 25

Para thyroid

Answer 25

Regulates the levels of calcium in your body. Does this by producing a hormone called parathyroid hormone

Question 26

Homeostasis

Answer 26

The process by which bodily conditions are maintained with certain range

Question 27

The process of homeostasis make use of negative feedback loop. A negative feedback loop consists of the following three stages:

Answer 27

Measure Compare Change

Question 28

Measure ( negative feedback loop )

Answer 28

The amount of glucose in the blood stream is constantly monitored by cells in the pancreas

Question 29

Compare (negative feedback loop)

Answer 29

Cells called alpha cells detect when the glucose levels in blood is low

Question 30

Change ( negative feedback loop)

Answer 30

Alpha cells cause glucagon to be release which acts to increase the glucose levels in blood

Question 31

Why is it called a negative feed back loop

Answer 31

Because the process always tries to negate any measured changes in order to return to acceptable levels

Question 32

Circulating hormones

Answer 32

Flow through the blood stream and different parts of the body

Question 33

Local hormones

Answer 33

Are not released into the bloodstream there for do not circulate through the body

Question 34

Describe the main stages of homeostasis of blood sugar levels

Answer 34

When a person's blood sugar is too high, their pancreas secretes more insulin. When their blood sugar levels drop, their pancreas releases glucagon to raise them.

Question 35

Name hormones released by pituitary gland

Answer 35

Adrenal Thyroid Ovaries Testes

Question 36

Explain the role of hormones and how they function

Answer 36

Role of hormones- help to control many functions such as growth, reproduction and repair Function of hormones- the body chemicals messengers sending signals into the bloodstream and tissues

Question 37

What’s the role of adrenal gland

Answer 37

Produces hormones that help regulate metabolism, blood pressure and immune system, response to stress and other essential functions
