What is the function of the Digestive System?

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

What is the function of the Respiratory system?

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

what is the function ofthe Urinary System?

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

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

supporting the body,


protecting soft body parts,


producing blood cells,


storing minerals and fats, and


permits flexible body movement and helps blood circulation

5/6 different functions

What is the function of the Nervous System?

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

The 3 main functions of the Endocrine System:

To produce hormones that regulate metabolism, growth and reproduction.

Structure: Mouth


Function: ?

mechanical Digestion and starts Chemical digestion of Carbohydrates.

Pharynx

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

Epiglottis

The covering to the glottis.


(it prevents food from entering the Larynx.

Esophagus

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

Stomach

Temp. food Storage


begins the digestion of proteins (via enzyme called pepsin)

Small Intestine

finishes carb and protein digestion


lipid digestion begins/occurs


nutrients absorbed

Pancreas

Produces insulin


pancreatic juice


digestive enzymes sent to small intestine

Liver (Function)

Destroys old RBC


store's nutrients


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


detoxifies blood



Gall bladder

Stores bile produced by liver


Sends bile to small intestine.

Gall bladder

Stores bile produced by liver


Sends bile to small intestine.

Large Intestine

absorbs water and salt to form feces


(primary function is to absorb water)

Organs in the Endocrine system:

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

What is an exocrine gland?

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

Mucosa

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.

submucosa

Ch 8 (Digestion)


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


→ located just beneath the mucosal layer.

Muscularis

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.

Respiratory Pathway

1. Nose → 2. Pharynx→ 3. Larynx→


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

Digestive Pathway

1). mouth → 2). Pharynx→


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

the three tissue layers of the Kidneys

1). Renal cortex


2). Renal medulla


3). Renal pelvis

Respiritory System and Homeostasis

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

Urinary System and Homeostasis

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