ANTH 242 Lecture Notes - Lecture 9: Birth Weight, Delayed Milestone, Malnutrition
Document Summary
For warm blooded species with a wide geographic range: average body size is larger in colder climates, more linear body shapes are better adapted to warmer climates. Suraface: volume ratio; smaller ratio=better heat retention. Warm-blooded organism in cold climates will have, on average, shorter appendages than those living in warm climates: examples: inuit versus masai. Cephalic index: cranial breadth/cranial length, warm: rounder. Nasal index: nasal width/nasal height, warm: short and broad nose, 3. Less tha(cid:374) (cid:1005)% of the (cid:449)orld"s populatio(cid:374) li(cid:448)es at greater tha(cid:374) 8,(cid:1004)(cid:1004)(cid:1004) feet. Example: hypoxia: short term response: temporary increase in respiration, long term response: rbc number increases, hemoglobin concentration increases, weight loss, growth development: Hyper-development of right ventricle of the heart. Delayed onset of menses (about 2 years) *possibly also related to nutrition though: measurement: chest circumference. Tissues can tolerate lower levels of o2: ethiopian highlands: Increase in production of co2 (vasodilator: 4. Nutritional adaptation: we all require certain levels of energy and nutrients to function.
