What slide is this?

Cardiac muscle; Found in walls of heart; Responsible for involuntary contraction of heart; Contains Intercalated discs(2 proteins gap junctions and desmosimes which hold cells tg)

What is in this slide?

Lung tissue; located inside thoracic cavity; responsible for gas exchange; alveoli is lined with simple squamous epithelium

what is on this slide? Location and function?

A. Artery B. Vein; found throughout body within circuitry system; 1.Arteries transport oxygenated blood away from heart. 2.Thick muscular walls; 1. Veins transport deoxygenated blood back to heart. 2. Thin walls/irregular shapes due to low pressure

what is on this slide?

Trachea; It’s extended from the larynx down to bronchi of lungs; Responsible for Air conduction; lined with pseudostrstified ciliated columnar epithelium

what is on this slide?

Stomach; located upper left portion of abdominal cavity; responsible for mechanical and chemical digestion

what is on this slide?

Small intestine; located distal to stomach; responsible for primary nutrient absorption

what is on this slide?

Large intestine/colon; framed around small intestine; responsible for recolonizing the colon with probiotic bacteria and white cells

what is on this slide?

KidneyA.Renal medulla B.Renal cortex; located in the back of abdominal cavity; responsible for filtering blood and remove metabolic waste

what is on this slide?

Testes; located within scrotum, outside of pelvic cavity; responsible for spermatogenesis

what is on this slide?

Ovary; located in pelvic cavity, lateral to uterus; responsible for oogenesis

what is on this slide?

Uterus; located in pelvic cavity, superior to the vagina; responsible for site of implantation + development of fetus

What type of information pass through the dorsal and ventral horns and roots of the spinal cord?

Dorsal horns/roots: Sensory(afferent) info

Ventral horns/roots: Motor(efferent) info

What are intercalated discs and where are they found?

These are specialized junctions between cardiac muscle cells. They are found in cardiac muscle tissue within the heart wall

What are the 3 layers of blood vessels and what type of tissue are they of?

Túnica interna,inner layer made of simple squamous; Tunica Media, middle layer of smooth muscle and elastic fibers; Tunica Externa, outer layer made of connective tissue

What structure is found within the intervenntricular groove?

Coronary blood vessels

Where is the cartilage located throughout the respiratory tract?

Found throughout the trachea and primary bronchi (C-Shaped rings)

What are goblet cells? Where are they found and what do they secrete?

Found in the respiratory tract epithelium; they secrete mucus to deal dust and pathogens

How does hyperventilation effect CO2

Decreases CO2 levels in blood

How does excercise effect CO2?

Increases CO2

How does bag breathing effect CO2?

Increased CO2

How did we detect CO2 levels being expired in lab?

Calcium hydroxide

What is rugae and where is it found? Function?

Folds that allow the stomach to expand when full

What is villi and where is it found? Function?

Found in small intestine; finger like projections that increase surface area for nutrient absorption

Where in the digestive system do digestion and absorption occur?

Digestion: Occurs in the oral cavity, stomach, and small intestine

Absorption: small intestine

What are segmentation and peristalsis and where do they occur?

Peristalsis: wave-like contractions that propel food forward; occurs through the almimentary canal

Segmentation: Localized mixing contractions; occurs in the small intestine

What are the 4 layers of the alimentary canal?

Mucosa: innermost, absorbs nutrients

Submucosa: connective tissue layer containing blood/lymph vessels

Muscularis externa: smooth muscle responsible for peristalsis and segmentation

Serosa: outermost layer, protects and reduces friction
