Small Intestine

Simple Columnar Epithelium

Small Intestine Tissue?

Absorption of nutrients and secretion of enzymes and mucus.

Simple Columnar Epithelium Function?

Columnar (tall, rectangular cells)

Intestine Cell Shape?

Cells have elongated nuclei usually located near the basal region

Columnar Cell Description?

• Digestion and absorption of nutrients

  • Carbohydrates → sugars

  • Proteins → amino acids

  • Fats → fatty acids and glycerol

• Absorbs vitamins, minerals, and most water from food

Small Intestine Function?

Cardiac Muscle

Involuntary, rhythmic contraction to pump blood throughout the body.

Cardiac Muscle Function?

• Pumps oxygenated and deoxygenated blood

• Maintains circulation and blood pressure throughout the body

Heart Function?

Kidney

Simple Cuboidal Epithelium

Kidney Tissue?

Secretion and absorption

Simple Cuboidal Function?

Cuboidal

Kidney Cell Shape?

Filters blood to form urine

Kidney function?

Intestine

Small Intestine - Ileum

Cartilage

Cartilage Den

Intestine

Oval

Cartillage cell shape?

Provides support, flexibility, shock absorption, and reduces friction at joints

Cartilage Function?

Chondrocytes

Cartilage Cell?

Bone / Osseous Tissue

Support, protection, mineral storage (calcium & phosphorus), and blood cell formation

• Provides structural support and protects vital organs

• Enables movement (acts as levers for muscles)

• Stores and releases minerals

• Houses bone marrow for hematopoiesis (blood cell production)

Bone Tissue function?

Spider-Like

Bone Cell Shape?

Areolar Connective Tissue

Binds and supports other tissues, wraps organs, holds tissue fluid, and allows diffusion of nutrients and wastes

Areolar Connective Tissue Function?

Muscular Striated Tissue

Voluntary movement, posture maintenance, and heat production

Muscular Striated Tissue Function?

• Muscles attached to bones (most common)

  • e.g., biceps brachii, triceps, quadriceps, gastrocnemius

• Tongue

• Pharynx

• Upper part of the esophagus

• Extraocular (eye) muscles

• Diaphragm

Muscular Striated Tissue Organs?

Areolar Connective Tissue Den

Human Cardiac Muscle

Human Bone Decalcified

Esophagus

Stratified Squamous

Esophagus tissue?

Squamous

Esophagus cell shape?

protects against mechanical abrasion

Stratified Squamous function?

• Conducts food from mouth → stomach (peristalsis)

• Protects mucosa from abrasion by swallowed food

• Secretes mucus from submucosal glands to lubricate the passage

Esophagus Function?

Intestine

Kidney
