There are many types of fluid contained within the human body. In this lesson, we explore the information that can be gleaned from synovial and serous fluids, semen and feces, and the means by which these specimens are collected and examined. ...
Other fluids found in the human body include cerebrospinal fluid, sweat, tears, the aqueous and vitreous humors of the eye, and body fluids related to human reproduction, such as semen and vaginal secretions. Blood cells are suspended in a fluid called plasma, which is mainly composed of ...
When a decrease in plasma osmolarity, volume, and pressure occurs, it stimulates the Renin-Angiotensin-Aldosterone System (RAAS), which functions to increase sodium reabsorption through the distal tubule. ANP is a hormone secreted by the cells in the atria of the heart and is stimulated when an...
Types of Tissue in the Body There are four main types of tissue in the body: Epithelial tissue Connective tissue Muscle tissue Nervous tissue Tissues of the human body Epithelial Tissue Epithelial tissue is a body tissue made of cells connected together in sheets that form barriers within the ...
tissue fluids. The most important reproductive tissues are the gonads (ovaries and testes), which produce the gametes (eggs and sperm, respectively). Hemopoietic tissues produce the cellular components of the blood. Among the important tissue fluids are lymph,cerebrospinal fluid, and milk (in ...
These fluids provide lubrication for intercourse. The vagina expands, and the clitoris enlarges. The nipples become hardened or erect. Orgasm (climax): At the peak of arousal, the muscles surrounding the vagina contract rhythmically, causing a pleasurable sensation. This is often referred to as ...
Fluid resuscitation is an indispensable procedure in the acute management of hemorrhagic shock for restoring tissue perfusion, particularly microcirculation in splanchnic organs. Resuscitation fluids include crystalloids, hypertonic saline (HTS), and synthetic colloids, and their selection affects the recovery ...
It is the only stress possible in a fluid at rest. See Pascal’s principle. Lithostatic pressure, the stress exerted on a body of rock by surrounding rock, is a pressure in Earth’s crust somewhat analogous to hydrostatic pressure in fluids. Lithostatic pressure increases with depth below ...
Each cell type found within the human body performs a diverse and unique set of functions, the disruption of which can lead to disease. However, there currently exists no systematic mapping between cell types and the diseases they can cause. In this stud
A condom is a thin, fitted tube worn over the penis during sex (external condom) or inserted into the vagina before sex (internal condom). It creates a barrier that keeps semen and other body fluids out of the vagina, rectum, or mouth. External condoms used to be known as male condoms...
