Respiratory System

Gionathan Zavala

Respiratory System function

Supply oxygen to blood so they can deliver by breathing. Inhale oxygen and exhale carbon dioxide.

Adaptation to gas exchange

The alveoli come in millions in each lung. Speeding up diffusion in the lung.

carbon dioxide transfer

Carbon dioxide is transferred into blood by being dissolved in solution or bound to proteins

Major disorders

Pulmonary edema- caused by excess fluids in the lung and can cause shortness of breathing, coughing, and can be fatal. It is uncommon and can be treated with giving oxygen to the body or taking blood pressure meds.

Immune system

Function of the immune system

The function of the immune system is to protect against pathogens or viruses.

Immune system terms

Pathogen - bacteria or virus

Active immunity - an immunity that protects by responding to a presence of antigen.

Passive immunity - short term immunity

Antigen - toxic or foreign substances that provoke an immune response

Antibody - protects against bacteria

Bursitis - caused by irritate of the bursae and may cause joint pain and is common.

arthritis - is caused by normal wear and tear and may cause pain in the affected area, and is very common and can be relived with pain relievers.

Muscular system


The function of the muscular system is for movement.


smooth - contractility of hollow organs

skeletal - pull on tendons

cardiac - propel blood

Explain skeletal contracts

Release of Ca2

exposure of myosin heads

create bridge


myosin heads change shape



Muscular dystrophy - carried by mother and replaces muscle tissue with fatty and is uncommon. Symptoms may vary from trouble with standing to loss of strength.

Mythopanthy - Myopathy is a disease that causes the skeletal or voluntary muscles to become weak or wasted. Is uncommon and symptoms may include muscle weakening

Nervous system


Sends communication throughout the body.

Meningitis - caused by inflammation of the brain and spinal cord. It is rare and symptoms are pain or rashes etc.

stroke - It is damage to the brain from interruption and is common and symptoms may include overreactive reflexes and etc.

Reproductive system


Produce egg cells and sperm


spermatozoa are produced from male primordial germ cells by way of mitosis and meiosis.


It involves the development of the various stages of the immature ovum. the cytoplasm is also unevenly divided.


Endometriosis - a condition involving colonization of the pelvic cavity with islands of endometrial tissue. It is very common and may cause pain in the lower abdomen.
