The entire cardiac cycle is as follows:
- Deoxygenated blood enters the right ventricle from the superior and inferior vena cava.
- The right atrium pumps the deoxygenated blood to the right ventricle.
- From the right ventricle, the deoxygenated blood moves to the lungs via the pulmonary artery.
- After gaseous exchange, the oxygenated blood returns to the heart into the left atrium via the pulmonary vein.
- From the left atrium, blood moves to the left ventricle.
- Oxygenated blood is pumped by the left ventricle into the aorta which supplies blood to all parts of the body.
- Deoxygenated blood, collected from the body again enters into the right atrium via the vana cava.
Answer:
Respiratory system and circulatory system.
The respiratory system allow living things to obtain oxygen from the air while the circulatory system allows oxygen to be carried around the body.
Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. ... Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.Mar 3, 2011
Answer:
Neuroimaging, or brain scanning, includes the use of various techniques ( Four of the most common types of brain scans are EEG, PET, MRI, and fMRI )to directly or indirectly image the structure, function, or pharmacology of the brain
Explanation:
Electroencephalography (EEG) is used to show brain activity under certain psychological states, such as alertness or drowsiness.
Positron emission tomography (PET) scans show brain processes by using the sugar glucose in the brain to illustrate where neurons are firing.
Magnetic resonance imaging (MRI) scans use echo waves to discriminate among grey matter, white matter, and cerebrospinal fluid.
Functional magnetic resonance imaging (fMRI) scans are a series of MRIs measuring brain function via a computer’s combination of multiple images taken less than a second apart. With this different scan it is possible for the function and structure of the brain to be determined.
