# ANATOMY AND PHYSIOLOGY ## 2ND SEMESTER - PRELIMINARY **Professor:** Dr. Fernando Gonzalvo ([email protected]) ### SUSPENSION - A heterogeneous mixture where the solute does not dissolve completely and remains suspended in the solvent. ### pH - A measure of the acidity or alkalinity of a solution on a logarithmic scale. - Normal pH: 7.4 (slightly alkaline) - pH of Blood: 7.35-7.45 - pH of Urine: 4.6-8.0 ### NUCLEIC ACIDS - Large organic molecules composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus, and they play essential roles in a cell. - It stores genomic information. ### 2 KINDS OF NUCLEIC ACID 1. DNA (Deoxyribonucleic acid) - 2 2. RNA (Ribonucleic acid) - 1 nucleotide ### HUMAN CELL **(Diagram of a human cell)** The image depicts a diagram of a human cell with various labeled organelles. **Organelles:** * Lysosome * Nucleus * Nuclear membrane * Chromosome * Mitochondrion * Cytoplasm * Golgi bodies * Cell membrane * Endoplasmic reticulum * Ribosomes * Peroxisome The diagram shows the different structures and components within a human cell. Each labelled organelle is clearly visible.
