Respiratory & Digestive Systems

Review PsTL 1082

What type of tissue is this?

Lip

Stratified squamous epithelium

Taste bud

What organ is this tissue from? What are 1, 2, 3, 4?

Esophagus

Note layers:1 - Mucosa (epithelium)2 - Submucosa3 - Muscularis4 - Serosa

L = lumen

What organ is this?What does this organ secrete?

Stomach

Secretions include: hydrochloric acid andPepsin (protein digestion)

What organ is this?What are layers 1, 2, and 3?

Small Intestine

1= lumen2 = villi3 = lymph tissue

Which organ is this?What are those white dots?

Large Intestine - Colon

Many goblet cells

Name the organ and something it secretes.

Liver gland = epithelial tissue

Liver - secretes bile (fat digestion)--Largest gland in your body.

Name the organ and two things it secretes.

Pancreasgland = epithelial tissue

Pancreas Both endocrine and exocrine gland.--Exocrine = digestive gland = Pancreatic enzymes--Endocrine = hormone Example = insulin

Identify these tissues

Identify these tissues

3=small intestine

4= liver

5=stomach

6=taste bud

7=pancreas

8=small intestine

Where is this tissue located?

What are the black arrows pointed at?

The colon and goblet cells

• 1 - cecum• 2 - ascending colon• 3 - transverse colon• 4 - descending colon• 5 - Sigmoid colon• 6 - rectum

• This is an x-ray of the large intestine.

• Note: Intestines are never as organized as the images you see in textbooks.

Where is this tissue located?

Small intestine (notice the villi!)

What are 1, 2, and 3 in this image?

• Q: What is this?• A: It’s an x-ray of the

stomach and small intestine.

• 1 = stomach

• 2 = duodenum

• 3 = jejunum

What is this tissue?

What are 1, 2, and 3?

the duodenum.

• 1 - mucosa - including villi

• 2 - submucosa -- includes connective tissues and glands

• 3 - muscularis layer that includes smooth muscle and nerves.


• A: Bile duct

What is the orange structure?What is its connection to the digestive

system?

• A: medulla oblongata

• A: Control gastric secretions, and several other digestive functions.

What is this tissue?What are 1, 2, and 3?

1 - Bronchiole (note cartilage) - transports air

2 - Pulmonary vein (note shape - not round)- transports blood

3 - Pulmonary artery (note shape - round)- transports blood

Bronchiole and Lung

Lung Tissue

Lungs contain many open space - alveolus

The lung is mostly epithelial tissue

Open space is for air

What is this?

Bronchus

1 - Hyaline cartilage

2 - lumen - the air passage

3 - Epithelial tissue lining the air passage

• What is the orange structure?

• What role does it play in the respiratory system?

• A: medulla oblongata

• A: Control of respiration / ventilation.

• Q: Identify the structure in blue, located at A.

A: carina

A: the diaphragm

What are the purple structures?

• A: intercostal muscles (muscles of “breathing” or ventilation)

• What is the purple structure?

• Q: Identify the structure shaded in blue.

• A: trachea

What is the purple structure?What is “A”?

• trachea• bronchi

• Q: Identify the structures located at A.
