GENERAL ATMOSPHERIC CIRCULATION A. PLANETARY PRESSURE BELTS 1. Equatorial calms (Doldrums) throughout the year a belt of low pressure surrounds the earth in the equatorial zone (except in the vicinity of the eastern Indian Ocean‚ East Indies and Australian region during the north hemisphere winter) most of air motion is vertical with light and variable winds having a slight westward drift 2. Subtropical calms or subtropical highs (Horse latitudes) characterized by high pressure

Kevin Kabuga BIO 160 10/28/14 Adult vs. Fetal Circulation CRN 93954 Prof. Kifle In adult circulation sequence‚ non-oxygenated blood enters the right atrium via the inferior and superior vena cava. The increase level of blood in the right atrium causes the tricuspid valve to open and drain the blood to the right ventricle. Pressure of blood in the right ventricle causes the pulmonic valve to open and non-oxygenated blood is directed to the pulmonary artery then to the lungs. The exchange of

circulatory systems work together to distribute oxygen to‚ and remove carbon dioxide from the cells of the body. The circulatory system and the respiratory system work closely together to ensure that organ tissues receive enough oxygen. Oxygen is required for cellular functions. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart‚ which pumps the oxygenated blood from the lungs to the body. Additionally‚ the two body systems work together to remove

The Heart and Circulation of Blood In this research paper‚ I will be analyzing the process of blood circulation within the human body. I will be focusing on the pulmonary circuit and the systemic circuit‚ as well as the relationship with the hepatic portal system. The combination of these systems allows the body to function properly and maintain unconscious homeostasis. I will also be talking about the effects that fitness and diet have on these processes. The pulmonary circuit passes already-used

Atmospheric Circulation This essay will describe patterns of atmospheric heating and circulation. When the surface air reaches the Equator‚ it gets heated and rises to the top of the troposphere‚ where it spreads back toward the poles. When it gets to the poles‚ it descends back to the surface again to complete the cycle. The heat of the Sun causes water to evaporate from lakes‚ rivers and oceans‚ as well as from the leaves of plants called (transpiration). But this water doesn

Thermohaline Ocean Circulation #1- What is The Thermohaline Ocean Circulation concept? The Thermohaline Ocean Circulation is when the circulation of the ocean is caused by heat and freshwater in the sea’s surface. This causes the mixing of heat and salt in the ocean. Thermo is temperature and haline is salt. Temperature and salt are the two factors that determine the sea’s density. The circulation causes differences in seawater density. The circulation also causes warm water from the southern hemisphere

There are many different circulation routes throughout our bodies that help our body stay functioning right. One of these major circulation routes is the fetal circulation route. The fetal circulation route is the route in which the blood flows from mother to fetus. It often uses the entire fetoplacential circulation which includes the umbilical cord‚ and the vessels within the placenta that carries the fetal blood. Basically the placenta is doing the work that the baby’s lungs will do after it is

William Harvey He concluded the systemic circulation of the blood accurately‚ he also concluded how the blood was pumped around the body from the heart and properties of blood. Harvey was an English physician who was the first to describe accurately how blood was pumped around the body by the heart. Ibn Al Nafis Ala-al-Din Abu al-Hasan Ali Ibn Abi al-Hazm al-Qarshi al-Dimashqi (known as Ibn Al-Nafis) was born in 1213 A.D. in Damascus. He was educated at the Medical College Hospital (Bimaristan
