Exam 3 Human Biology

Front 1

What is the function of the Digestive System?

Back 1

To hydrolyze(or breakdown using water) macromolecules into their subunit molecules.

Front 2

What is the function of the Respiratory system?

Back 2

Ensuringthat oxygen enters the body and carbon dioxide leaves the body.

Front 3

what is the function ofthe Urinary System?

Back 3

I excretes metabolic waste from the body while maintaining salt, water, and pH balance/homeostasis.

Front 4

What are the functions ofthe Skeletal and muscular system(s)?

Back 4

supporting the body,

protecting soft body parts,

producing blood cells,

storing minerals and fats, and

permits flexible body movement and helps blood circulation

Hint 4

5/6 different functions

Front 5

What is the function of the Nervous System?

Back 5

the reception and processing of sensory information from external and internal environments.

Front 6

The 3 main functions of the Endocrine System:

Back 6

To produce hormones that regulate metabolism, growth and reproduction.

Front 7

Structure: Mouth

Function: ?

Back 7

mechanical Digestion and starts Chemical digestion of Carbohydrates.

Front 8

Pharynx

Back 8

passageway where food is swallowed (hollow space in the back of the throat).

Front 9

Epiglottis

Back 9

The covering to the glottis.

(it prevents food from entering the Larynx.

Front 10

Esophagus

Back 10

Rhythmic muscular contractions Called peristalsis) push the chewed food(bolus) through to the stomach.

Front 11

Stomach

Back 11

Temp. food Storage

begins the digestion of proteins (via enzyme called pepsin)

Front 12

Small Intestine

Back 12

finishes carb and protein digestion

lipid digestion begins/occurs

nutrients absorbed

Front 13

Pancreas

Back 13

Produces insulin

pancreatic juice

digestive enzymes sent to small intestine

Front 14

Liver (Function)

Back 14

Destroys old RBC

store's nutrients

stores glucose as glycogen b breaks down glycogen to glucose between eating periods

detoxifies blood

Front 15

Gall bladder

Back 15

Stores bile produced by liver

Sends bile to small intestine.

Front 16

Gall bladder

Back 16

Stores bile produced by liver

Sends bile to small intestine.

Front 17

Large Intestine

Back 17

absorbs water and salt to form feces

(primary function is to absorb water)

Front 18

Organs in the Endocrine system:

Back 18

1) Hypothalamus

2) Pituitary Gland

3) Thyroid

4) Parathyroid

5) Adrenal Glands ( Ad= Above, Renal= Liver)

6) Gonads

7) Thymus

7) Thymus8) Pineal Gland

8) Pineal Gland

Front 19

What is an exocrine gland?

Back 19

A gland that secretes hormones to be carried to the lumens of other organs or outside the body.

Front 20

Mucosa

Back 20

Ch.8 (Digestive tract)

inner mucous membrane layer that secretes mucous and digestive enzymes into the lumen of the GI tract to chemically digest food.

Front 21

submucosa

Back 21

Ch 8 (Digestion)

A broad band of loose connective tissues that contains nerves, blood, a lymphatic vessels.

→ located just beneath the mucosal layer.

Front 22

Muscularis

Back 22

Ch8 (Digestion)

→3rd layer of digestive tract wall.

Two layeres of smooth muscle that contract cross sectionally (one horizontally and the other vertically) to move the digesting bolus down the lumen of the digestive tract/intestine.

Front 23

Respiratory Pathway

Back 23

1. Nose → 2. Pharynx→ 3. Larynx→

4. Trachea→ 5. Bronchus→ 6. Bronchioles→ 7. Alveoli

Front 24

Digestive Pathway

Back 24

1). mouth → 2). Pharynx→

3). esophagus → 4).stomach → 5). Small intestine→ 6). large intestine → 7). Rectum →8). Anus

Front 25

the three tissue layers of the Kidneys

Back 25

1). Renal cortex

2). Renal medulla

3). Renal pelvis

Front 26

Respiritory System and Homeostasis

Back 26

The kidneys, lungs work together to maintain the acid-base balance of the blood.

Front 27

Urinary System and Homeostasis

Back 27

Kidneys excrete nitrogenous waste, Maintain water-salt balance, and maintain acid-base (pH) balance of the blood.
