Depends if your talking about interstitial fluid or lymph: As per starling forces: the oncotic pressure of the late capillary plus hydrostatic pressure of interstitial space, would be higher than oncotic pressure of interstitium [though I dunno why since intertitial GAGs are very water hungry and they are responsible for the negative (hydrostatic?) ...

There are 2 reasons for light to appear red through the eyelids. 1) Eyelids get a rich supply of blood which contains iron (in hemoglobin). The iron in blood absorbs all colors of light but reflects red light (reference). 2) Our tissue transmits red wavelengths of light very well, but it doesn't transmit blue or wavelengths of light towards the blue end of ...

Short answer, your eyelids does not block all light. Since they are only a thin layer of skin, the light is able to pass through although not completely obviously. Since the eyes are still completely functional when you close them, only covered by the eyelids, you are able to see when light strikes your face.

Good question... so the condition is height not width. remember the more taller a person is, the more chondrocytes of epiphysial plate (disk) has prolifrated and calcified (in the 12-17) (puberty phase) because you know every long bone has two epiphysial plate distal and proximal and the will be calssificated so it's the chondrocytes that prolifricates (do ...

The pathophysiology of orthostatic hypertension has not been elucidated. It is believed it involves activation of the sympathetic nervous system [1], vascular adrenergic hypersensitivity and diabetic neuropathy [2]. High levels of plasma atrial natriuretic peptide and antidiuretic hormone were observed in children [3]. Hypovolemia causes: ...

Healthy young males have estradiol levels in the area of 20-30 pg/ml. Also, estrogen is a group of hormones, including estradiol and estrone for example. You shouldn't think of any hormones as women hormones or men hormones really, as both genders have them all, albeit in different proportions, and generated often through different pathways/organs. this ...

I'm going to answer the question of whether aestivation/hibernation can be activated in humans or other apes, because it's more interesting. Mammals, as a clade, have three major subgroups. Bats, shrew-likes, rodents, and then everything else including primates. One family of the shrew-likes hibernates, some rodents(but not all) and some bats can hibernate ...

I am not sure I fully understand your question, it's a little unclear. But if I understand the question correctly it is how to we coordinate movement on both sides of the body? Well this can occur because we have connections between both hemispheres of the brain. The major connection is called the corpus collosum, this is a white matter tract that allows ...

What is the mechanism of antiperistalsis that occurs during vomiting? Emetic agents in the bloodstream stimulate chemoreceptors in area postrema and nucleus tractus solitarius [1]. Nucleus tractus solitarius is connected to motor neurons in ventral medulla and hypothalamus [1]. Esophageal and gastric peristalsis is inhibited. Small bowel peristalsis ...

It is to do with the extend of the damage to the glomerulus. In nephrotic syndromes the glomerulus is damaged so that there is death of the podocytes. This happens to sufficiently high number of podocytes so that large proteins such as albumin and clotting factors can leak out causing large proteinuria. Damage to the basement membrane may also occur, such as ...

Is this possible or am I just hallucinating? Certainly possible, but I'd peg the mechanism closer to Sensitization or De-sensitization of the neurons involved so that when you finally ingest some salt the sensation is different. The sodium and chloride levels of the ingested material wouldn't have a direct effect on the level of De-/Sensitization, but ...

Ischemia leads to tissular hypoxia and glycopenia due to an insufficient blood flow (e.g. due to atherosclerosis or thromboembolic diseases). Ischemia always result in hypoxia. Hypoxia can occur without ischemia (e.g. due to anemia). Tissular glycopenia can occur without ischemia (e.g. due to hypoglicemia). Ischemia is a shortage in blood supply. ...
