Effect of blood chemistry - stimuli, hyperventilation response and hypoventilation response

By: HWC, Views: 9028

• Respiratory rate is effected by changes in: • Blood pH. • Blood Pco2. • Blood P02. • Chemoreceptors in the central and peripheral nervous systems closely monitor the Fr, CO2 and 02 levels in blood. • Changes in frequency of impulses from Chemoreceptors affect respiratory r...

The brain’s cerebral cortex is the outermost layer that gives the brain its characteristic wrinkly appearance. The cerebral cortex is divided lengthways into two cerebral hemispheres connected by the corpus callosum. Traditionally, each of the hemispheres has been divided into four lobes: front...

Dietary Cholesterol & LDL

By: HWC, Views: 8676

LDL comprises 60–70% of total blood lipoproteins and is responsible for carrying cholesterol particles throughout your body. Having a lot of cholesterol carried by LDL lipoproteins is associated with an increased risk of heart disease. In fact, the higher the level, the greater the risk. ...

Malaria is caused by the sporozoan, Plasmodium. It is transferred to humans by mosquitoes. When an infected mosquito feeds, infective sporozoites move from her salivary glands into the human body. The bloodstream carries the sporozoites to the liver. Here, they reproduce asexually and...

Protein catabolism (Krebs cycle) and Protein anabolism (protein synthesis)

By: HWC, Views: 9832

• Deaminated acids are brought into the Krebs cycle to be oxidized to CO2 and H2O. • Before entering the Krebs cycle, the deaminated acids are converted into intermediate products (pyruvic acid, acetyl coenzyme A, carbonic acids). • In the Krebs cycle, amino acids are oxidized to form r...

Hemodynamics Animation
