It has been demonstrated that‚ as opposed to the intrarenal arteries‚ the intrarenal veins show no segmental arrangement at all‚ there being a free anastomosis of the venous system throughout the kidney. These anastomoses occur at different levels between the stellate veins (cortex)‚ between the arquate veins (base of the pyramids) and between the interlobar veins (close to the renal sinus). There are also anastomoses around the calyceal necks that join a longitudinal system

When veins do not work properly‚ it is called venous insufficiency. This means that the veins are not effectively sending the blood back to the heart. The severity of venous insufficiency differs with each person. If the problem goes untreated‚ the person may feel continuous symptoms of pain‚ swelling and fatigue in the legs and ankles. If the problem is advanced there are other symptoms such as leg ulcers‚ superficial thrombophlebitis‚ spontaneous bleeding and‚ possibly‚ deep vein thrombosis. Our

and structure There are three types of blood vessel‚ Arteries ‚ veins and capillaries. Each of them have different functions involved in carrying blood around the body . Arteries are blood vessels that transport blood away from the heart‚ veins are blood vessels that transport blood to the heart and Capillaries are extremely small vessels located within the tissues of the body that transport blood from the arteries to the veins. they must be constructed for carrying fluids over long distances‚

Arthropod (crayfish) Dissection Megan Williamson period: 3 4/29/13 Objectives: The purpose of this lab was to study and observe the organs in a crayfish and be able to name them. Introduction: Crayfish belong to the kingdom animilia‚ phylum arthropod and class crustaceans. The body is divided into three parts‚ the body‚ the head‚ thorax‚ and abdomen. The head and thorax are apart of a segment called cephalothoraxes‚ which is covered by the carapace made of chitin

Topic 1: I believe using abbreviations can truly help communications between health care professionals‚ because it makes it easier to convey what you are trying to say. For example‚ instead of saying or writing down “cardiopulmonary resuscitation” you could say “CPR”. This also helps speed up the process when a transcriptionist copies down a report; they don’t necessarily have to write out the full meaning and the physician who reads the report will still have a full understanding of what it

the femoral vein‚ which is located in the upper thigh and pelvic region of the human body (Healthline‚ 2014). While traveling through the femoral vein‚ you will notice that it is one of the largest in the venal system. As you may also know the femoral vein will return oxygenated blood to the heart and lungs. From the femoral vein‚ we will be traveling up the external iliac vein. Once we enter the external iliac vein‚ we will be carried through the abdomen. From the external iliac vein we travel

The purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the
