body systems Flashcards
How does blood and oxygen flow through the body
Right side of the heart receives oxygen poor blood from veins and pumps it into the lungs. Where it picks oxygen and gets rid of carbon dioxide. Left side of the heart receives oxygen rich blood from lungs and pumps it in the arteries to the rest of your body.
External and Internal respiration
External respiration occurs in lungs where oxygen diffuses to the blood and carbon dioxide diffuses to the alveolar air. Internal respiration occurs in metabolizing tissue where it diffuses out the blood and where carbon dioxide diffuses out cells.
Lungs-Heart-Blood connection
The pulmonary arteries moves blood from heart to lungs where it picks up oxygen. Pulmonary veins move blood from lungs to the heart’s left side, where it can be moved to the rest of the body. The areolas send newly oxygenated blood from the heart’s left side to the rest of the body.
Purpose of Arteries and Veins
Arteries move blood away from the heart. Veins return blood back to the heart.
Respiratory system
The Respiratory system is the network of organs and tissue that help breath.
Airways
Lungs
Blood vessels
The muscles of the lungs are also a part of the Respiratory system. The parts work together to move oxygen all around the body and clean out waste.
Circulatory system
The Circulatory system is an organ that allows blood to flow and move nutrients, oxygen, carbon dioxide, hormones and blood cells to and from the cells in the body to give food and help in fighting diseases.
Digestive system
The GI tract is a chain of hollow organs in a long, twisting tube from the mouth to the anus.
Mouth
Esophagus
Stomach
Small / Large intestine
Anus
The Liver, Pancreas and the Gallbladder are the solid organs of the Digestive system.
Excretory system
The Excretory system is the setup of the body that does the excretion, the bodily way of discharging wates. It is responsible for removal of wastes produced by the homeostasis.
Sensory system
The Sensory system is part of the Nervous system responsible for processing sensory information.
Sensory neurons
Neural pathways
Part of the brain involved in sensory perception

Gastrointestinal infection
Gastrointestinal infection happens in the Digestive system, happens when bacteria causes an infection in the gut. This causes inflammation in the stomach and intestines. The treatment for this is antibiotics and staying hydrated.
