Biology Lab Final (Cardiovascular System) Flashcards
Frog - Ventricle
Chamber of frogs heart that pumps blood out of the heart to the lungs and other parts of the body
Frog - Lungs
Pair of lungs serve as the organs of aerial respiration. The lungs are not just respiratory organs, but they are also hydrostatic organs, allowing the frog to float in water when expanded. The respiratory fact allows air to enter and exit the lungs.
Frog - Atria ( L/R)
RIGHT ATRIA
- chamber of the frogs heart that recieves blood from the sinus venosus
LEFT ATRIA
- The chamber of the heart that receives blood from lungs
Shark - Spiracle
Used to take in water and ventilate the gills, ingest microscopic food particles.
Shark - Gills
Allows fish to take in oxygen from surrounding water and eliminate carbon dioxide from the blood
Shark - Ventricle
Its function is to pump oxygenated blood to the rest of the body. I
Shark - Atrium
(RIGHT) Its primary function is to receive deoxygenated blood returning from the body and pump it into the ventricle.
(LEFT) received oxygenated blood from lungs
Shark - Aorta
Carries oxygenated blood to the heart
Pig - R/L Ventricles
RIGHT VENTRICLE
Receives deoxygenated blood from the right atrium.
Contracts to pump this deoxygenated blood to the lungs via the pulmonary artery for oxygenation.
The right ventricle has thinner muscular walls compared to the left ventricle because it primarily pumps blood to the nearby lungs rather than throughout the entire body.
LEFT VENTRICLE
Receives oxygenated blood from the left atrium.
Contracts forcefully to pump this oxygen-rich blood into the aorta, the body’s main artery, which then distributes it to all parts of the body.
The left ventricle has thicker muscular walls compared to the right ventricle to generate enough force to pump blood throughout the systemic circulation.
Pig - Caudal / Cranial Vena Cava
Cranial Vena Cava:
The cranial vena cava is the large vein that carries deoxygenated blood from the upper body regions, including the head, neck, and forelimbs, back to the heart.
Caudal Vena Cava:
The caudal vena cava is the large vein that returns deoxygenated blood from the lower body regions back to the heart.
The caudal vena cava also empties into the right atrium of the heart.
Pig - Larynx
a structure located in the throat, also known as the voice box. It plays several important roles in respiration, vocalization, and protecting the airway.
Pig - Trachea
The function of the trachea in pigs is to provide a passageway for air to travel between the larynx and the lungs,
Pig - Lung
The function of the right and left lungs in pigs is to facilitate efficient gas exchange during respiration, ensuring the intake of oxygen and removal of carbon dioxide, while also supporting lung expansion, immune defense, and surfactant production.
Pig - Diaphram
The diaphragm moves up and down as pigs breathe through a process of contraction and relaxation. allows air to enter and exit their lungs
Sheep Heart - L/R Auricles
Upper chambers of the heart that recieve and fill with blood returning to heart in the veins. (R Atrium recieves from body - L Atrium from lungs or pulmonary veins)
